Cleaning
Internal Cleaning
No internal cleaning of the GAS-Guard is required; doing so may cause damage the internal
components and void the warranty.
External Cleaning
No external cleaning of the GAS-Guard is required. If external cleaning is desired, water is the only
recommended cleaning solution. Direct spray of high-pressure water onto the GAS-Guard door seal,
LED’s, oil/helium bulkhead fittings and cable glands should be avoided.
